SC connector and FC interface

To connect an SC connector to an FC interface, you can use an SC-to-FC fiber optic adapter or a hybrid SC-FC patch cable.

Understanding SC and F

C ConnectorsSC (Subscriber Connector) features a square body with a push-pull latch, a 2. 5 mm ceramic ferrule, and is widely used in telecom, FTTH, and data center applications for its ease of installation and reliable performance.

F

C (Ferrule Connector) has a round, threaded body with a 2. 5 mm ferrule, providing secure connections in high-vibration environments such as industrial or long-haul telecom systems.

F

C connectors are known for precise alignment and low signal loss but are less common in modern high-density data centers compared to SC or LC connectors.

Connecting SC to FC

Since S

C and FC connectors have different shapes and locking mechanisms, direct mating is not possible. You have two main options: SC-to-FC AdapterA small mechanical device that allows an SC plug to mate with an FC receptacle. Maintains proper ferrule alignment to minimize insertion loss and reflection.

Available in single-mode or multimode versions, and with different polish types (UPC or APC) to match the fiber performance requirements. Hybrid SC-FC Patch CableA fiber optic cable terminated with an SC connector on one end and an FC connector on the other. Provides a ready-to-use solution without requiring an adapter.

Useful for connecting equipment with different connector types in patch panels or test setups.

Considerations

Polish Type Compatibility: Ensure both connectors use compatible polish types (UPC or APC) to avoid high return loss or signal reflection. Fiber Type: Match single-mode or multimode fiber to maintain optimal transmission. Insertion Loss: Using an adapter or hybrid cable introduces minimal additional loss if properly installed, typically less than 0.

5 dB. Environment: FC connectors are preferred in high-vibration or industrial settings, while SC connectors are easier to handle in standard telecom racks. By selecting the appropriate adapter or hybrid cable, you can seamlessly connect SC-terminated cables to FC interfaces while maintaining signal integrity and mechanical reliability.
